`nvmRovr-.D HAY-ELEVATQR.

The Schedule referred to in these Letters. Patent and making part of thesame.

-and l)elivcry-Apparatns57 and we do hereby declare that the followingis a full and exact description .thereof, reference heilig had to theacco nip .ftnying drawings, v

and to the letters of reference marked ther-con.

Figure l represents a sidoI elevation of the skeleton or frame-work ot'a barn to which my apparatus has been attached;

Figure 2, a side. elevation of the windlass;

Figure 3, a front view of' the same;

Figure 4, a side elevation of the carriage and the devices by which' itis held in the desired position during the hoisting-operation; p

Figure `5 represents a front view of the same, in which the red outlinesindicate how the carriage is 4released at the end of thehoisting-operation; and

Figure 6 is a plan or topview of thesaine, the red outlines 'indicatingthe same, as in the preceding figure. f

Corresponding letters referto corresponding parts in the severalfigures.

Our invention relates to portable hoisting-apparatus,

' which may be used for loadi'u g an d unloading hay, straw,

manure, 85e., or for excavating purposes, saidlapparatus beingsoconstructed as to deliver the raised substances It consists in theconstruction and arrangement of its several parts, as hereinafter morefully described.

To illustrate the operation of our apparatus,we have shown it in thedrawings as attached to a barn.

A represents the wire rope or guy on which the cary riage is placed.`One end of it is secured, by means of a hook-and-eye bolt, to one end ofthe barn, under the roof,.and it is then extended along horizontally tothe vother end of the barn, and, after it has been passed over the blocka, which is suspended from the rafters, it is attached to the drum of awindlass and wound upon it until it has the required tension.

B represents the windlass, which may be of the most simpleconstruction,its sole object being-to hold the wire rope or guy at the necessarytension. It is secured under the block a to a cross-beam of the barn inany convenient manner.

C represent-s' the frameof the cam-inge, which may be made ofsheet-metal, and must have theneccssary strength and dimensions to carrythe different parts which are attached to it.

Near each end and in its upper portion it has grooved rollers, c c,which are placed between the sides of the frame and revolve on shafts,which are secured in the vtache-d therefrom-.-

frame in such a manner that they can be yeasily de These grooved rollersrest on the guy, and in order to keep thc carriage always in properposition on it a 'friction-roller, c', is place( in the frame betweenthe groovcd rollers, and in such a manner that as the latter rests onthe upper surface of the wire rope, its lower surface lies on top of thefriction-roller. v

D represents the pulley', which revolves on a shatt secured to the sidesof the frame of its carriage on one end of it, and in its lower portion.Over this the tackle passes by means of, which substances may be raised.p

E E represent two levers ot' the form clearly 'shown in fig, 5 of thedrawings. They are hinged to lugs on the ii'am'e of the carriage in sucha manner that their long curved arms extend downward vertically, andthat that portion of the tackle to which the cone I, hereafter to bedescribed, is attached, may move between them. The inner sides of thesearms of the levers may be made concave where they are madeto moet, thussurrounding the tackle; r

"To the ends of the short arms, the latches Fare .hingcdgand they areacted o'n by the springs c e, which are fastened to the Sides of theframe, so as to throw them apart and bring the long arms together.

F F representA the latches or hooked levers, which are pivoted on eachside of the frame to lugs in a horizontal position. One end of them isattached to the vin fig. 6, extend a short distance beyond the carriageand hook over the doublccatch. G represents the double catchwhich isclamped to the wire rope at the proper point, and in such a manner that,as the carriage is drawn up to it, the latches.

F will vhook over the catches and hold thc carriage in the properposit-ion until they are again released from it by the action of thecone.

The catch consists of two plates of metal, the straight inner sides ofwhich have longitudinal grooves, in which the wire rope lies, whentheyare clamped to it. On the outer sides, on one end, theyare providedwith hooks, as shown in fig. 6. 1 I

H represents the tackle, which is passed between the lsuspended arms ofthelevers E over the pulley D of the carriage along in a horizontaldirection to the i end of the barn over the pulley of the block h, whichis suspended from the rafters, thence in an oblique 'direction tothe'block h, which is attached to the side of the barn, and then down tothe block h2, which is secured to the iioor of the barn.

I represents the cone, which is attached to that end of the tackle whichhangs from the pulley of the carriage, and t which the weight to beraised is attached.`

i It slips over the tackle, ,and may be secured to it at any to the endVof a rope, k, said rope passing over the block It, which-is suspendedfrom the rafters directly above the guy and backof the double catch andcarriage, and thence to that end of, the carriage nearest to thecatclnwhen it is secured to said carriage in any convenient manner.

The weight must be heavy enough to draw the carriage back to the catchwhen the load has been deposited. I

The operation is as follows:

A load of hay or grain is drawn directly under the carriage di' theapparatus. The cone is secured to the tackle, so that it will releasethe carriage when the hay or grain has been raised to the necessaryheight. The hay is now taken up by means of a fork attached to the endof the tackle, which hangs down from the carriage and raised byemploying the necessary power at the other end of the tackle until thecone is drawni between the levers E, separating them, and therebyreleasing the latches from the double catch.

The carriage will at once be drawn along the guy 'up to the point whereit is desired to deposit the hay,

'its latches becolne engaged thereto by the action of the counterweight.

When it is desired to remove the apparatus from one place to another7the tackle and its blocks can be taken down first, then the guyandwindlass removed, and lastly the carriage and counterweight.

Some of the advantages of this apparatus consist in its peculiarconstruction, by .which we are enabled to transport it from place toplace with ease and rig it up at a small expense, and that it willdeliver raised weights at any given point.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, isl l. Thedoublecatch G, substantially as and for the purpose described.

A2. The combination of' the cone I, tackle H, levers E, springs e,.latches F, and` double catch G, substantially as and for the purposeset forth.

In testimony whereof, we have signed our names toA these specificationsin the presence of two subscribing witnesses.
